Title:
COLD CATHODE LAMP, ILLUMINATING DEVICE FOR DISPLAY COMPRISING SAME, AND DISPLAY
Document Type and Number:
WIPO Patent Application WO/2007/132543
Kind Code:
A1
Abstract:
Disclosed is a cold cathode lamp comprising a light-transmitting insulating tube
(1), first and second internal electrodes (2, 3) arranged inside the insulating tube,
first and second external electrodes (4, 5) arranged outside the insulting tube
and respectively connected with the first and second internal electrodes, first
and second insulating bodies (8, 9) respectively covering the first and second
external electrodes, a first counter electrode (10) arranged opposite to the
first external electrode via the first insulating body, and a second counter electrode
(11) arranged opposite to the second external electrode via the second insulating
body. The first (second) counter electrode has a portion which does not face the
first (second) external electrode, and the space between this portion and the
insulating tube is filled with the first (second) insulating body. A plurality of
such cold cathode lamps can be lighted by being connected in parallel with a power
supply. In addition, generation of corona discharge near the outer peripheries of
the counter electrodes can be suppressed.
